SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 320,175, dated June 16, 1885.

(No model.)

To all whom z' may concern:

Be it known that I, JOSEPH R. RUSBY, a citizenof the United States, residing at Bloom` field, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Sash-Fasteners, and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, makinga part of this specification, and to the letters and figures of reference marked thereon.

illy invention is an improvement in windowfastenings, and aims to provide a simple construction of fastening, by which the sashes may be firmly locked, so that they cannot be opened by an instrument inserted between them, and by which the-sashes will be drawn closely together, yet the warping of the sashes or their frames will not throw the parts of the fastener out of operative position.

To these ends the invention consists in certain novel constructions and combinations, which will be hereinafter first fully described, and then pointed out in the claims.

Referring` to the drawings, Figure l is a plan view of the fastener in position. Fig. 2 is a sectional view on line x x, Fig. 1, and Fig. 3 is a detail view representing the cylinder and a portion of the supporting-plate.

The fastening` is show'n on the meeting-rails A a of two sashes. On the rail A, I tix the supporting-plate B, which may be provided in one end with a stop-notch, b. Between the ends of the plate B, I form the circular recess C, which may be surrounded by a rail-like projection, c, as mostclearly shown in Fig. 3. Through the plate B, centrally of the recess C, I form an opening or perforation, D, the lower end of which is enlarged, as shown in Fig. 2.

' The cylinder E is formed with a shoulder, e, which rests on the upper side of the plate B, and usually on the rail c. A cylindrical projection, E, extends below this shoulder e, and is fitted into the recess C. This projection F is provided centrally with a stud, f, which enters perforation D, and is punched or otherwise swelled out at its lower end tofill the enlarged lower end of opening D, and so operate to retain the cylinder on and to the This construction, it will support-iiig-plate.

be seen, forms a convenient and durable pivot for the cylinder, and suffices to connect such part to the supporting-plate without the intervention ot' separate connecting-bolts. It is manifest, however, that the cylinder might be pivoted in other ways, if desired.

One end of the cylinder is closed by a plate, G, which is provided with an opening, g, for the passage of the latch II. This latch is connected at its inner end to the plunger I, between which and the inner side of end plate, G, bears the coil-spring There desired, this spring might be of rubber or of equivalent construction. This spring, it will be seen, serves to give the latch a tension toward the cylinder, and it is held from movement through said cylinder by a limiting shoulder or shoulders, 71. Near its outer end the latch is provided with a depending lug, J, formed, preferably, with the wings j and k, the latter being extended horizontally and to the rear, as shown.

The catch-plate L is fixed on the rail a, and comprises a base-plate, M, an upright plate, N, curved horizontally, a top plate, O, projected horizontally from the upper edge of the plate N, and the plate I?. This catch-plate is cast in one piece. The edge of plate O is curved ecceutrically to the center of motion ofthe latch, with its central portion or crown farthest from said center, at which central part I form the plate O with a stop-notch, o. The brace-plate P has its upper edge flush with that of the top plate and in line with the stop-notch o, so that when the lever is adjusted to the position shown in Fig. 2, said plate P will support it and relieve said latch of the strain it would otherwise receive by leverage in case one should attempt to raise the sash when fastened.

In operation, when unfastened, the latch is held by its lug J engaging notch b of the supporting-plate. To fasten, the latch is moved to the position shown, the wing 7; of the lug J bearing under, and the wing]- against, the edge of the plate O. Vhere the latch registers with notch o the wing y' enters the same, as shown. This prevents the unlatehing of the device by a knife-blade or other instrument inserted between the meeting-rails.

The spring operates to draw the sashes snugly together, and at the same time permits ICO a sufficient adaptability of the device tol enable its proper operation on sashes which have slightly Warped, or the frames of which have warped and so displaced the sashes.

While I prefer the cylinder and the arrangement of the spring before described, it is manifest that modifications may be made without departing from' the broad principles of the invention. For instance, the inner end of the latch 'may have an elongated slot fitted over the pivot, on which said latch may turn so the latch can slide longitudinally on such pivot, and a spring might be arranged to bear between the pivot and the rear end wall of the elongated slot of the lever; but I prefer the construction as shown and before described. The cylinder may also be pivoted directly to or on the meeting-rail.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

l. The combination, with the supporting-v plate provided at one end with a stop-notch and the catch-plate provided with a stopnoich, ofthe latch pivotally supported ou the supporting-plate and provided with a depending lug adjustable into engagement with the notch of either the supporting or catch plate, and a spring whereby said latch is given a longitudinal tension, substantially as set forth. 2. A window-fastening consisting of the catch-plate having a stop-notch, the pivoted l jected into and held within the perforation thereof, the latch, the actuatingspring, and the catch-plate,I substantially as set forth.

4. As a new and improved article of manufacture, the catch-plate herein described, consisting of the base-plate, the curved upright plate mounted thereon, the top plate having a curved edge and provided with astop-notch, and the brace-plate mounted on the base=plate, and having its upper edge flush with that of the top plate and in line with the stop-notch therein, substantially as set forth.

In testimony that I claim the above I have' hereunto subscribed my naine in the presence of two witnesses.

JOSEPH R. RUSBY.
